From highest to lowest chance of spawning, the categories displayed are: Ultra High, Very High, High, Decent, Poor, Very Poor. This category is followed by the name of the ore, and a number in parentheses, which given in parts per thousand or 'PPT' (per mille - note there are two zeros below the slash, ‰, as opposed to a normal percent sign, %, which has one zero below). This number represents the amount of blocks in 1000 (the amount of blocks in a chunk) that may be of that specified ore should it have spawned (miniscule readings indicate that the ore is NOT available in the current chunk, but may be available in the neighboring chunks).
